ABSTRACT
The paper proposes a data-driven fault-tolerant control (FTC) strategy to construct and accommodate the bias on ambient temperature measurements in supermarket refrigeration systems. The bias, which is caused by direct or indirect exposure of the sensor to the sun, can have a significant impact on the refrigeration system's energy consumption. Based on analysis of the real data a comprehensive model of the bias is developed and then used to generate realistic scenarios for testing the proposed FTC method. The FTC method uses a feed forward Neural Network (NN) as a black box model. The model is trained by active injection of perturbation signals during the night operations. During the Monte-Carlo tests, the strategy was implemented in a Plug & Play manner, demonstrating that substantial energy savings can be achieved during summer periods.
ABSTRACT
BACKGROUND: Admission of patients in coronary care units can lead to sleep disorders due to advanced monitoring and interventions. Inappropriate sleep quality in cardiac patients may be influenced by their health status. So, this study was performed to detect the effect of Milk-honey mixture on sleep status of acute coronary syndrome patients in the coronary care unit. METHODS: A clinical trial study (registered under IRCT.ir with identifier no. IRCT201309285134N7) was conducted with 68 hospitalized patients with the acute coronary syndrome in the coronary care unit of a referral hospital in Semnan, Iran. After hospitalization of patients and selected eligible patients, sleep status of them was measured by Richards-Campbell Sleep Questionnaire in range of 0 to 100 score. Then patients were divided into the intervention and control groups randomly. Patients in the intervention group were received milk-honey mixture twice a day for three days. The control group patients were received routine care. In the third day, sleep quality of patients in the two groups was measured again. Finally, the data were analyzed by descriptive and inferential statistics. RESULTS: The mean and standard deviation of patients' age was 63.12 ± 32.63. There was no significant difference in sleep scores on the first day of admission between the two groups (P = 0.914). But, on the third day of admission, there was a significant difference in sleep scores between the intervention and the control groups (P = 0.001). CONCLUSION: The mixture of milk and honey improves the sleep status of patients. So, it can be considered as an effective and affordable intervention to enhance the sleep quality of patients with the acute coronary syndrome in coronary care units.

INTRODUCTION: Estrogen has a protective role on auditory function. It may have an excitatory action on auditory nerve fibers and can have a neuroprotective effect. Progesterone has a mainly inhibitory action on the central nervous system, which may balance the mainly excitatory action of estrogen. OBJECTIVE: To determine changes in hearing performance with pure tone audiometry (PTA), tympanometry, distortion product otoacoustic emissions (DPOAEs), and auditory brainstem responses (ABR) as hormonal changes occur from follicular to luteal phase. MATERIALS AND METHODS: Twenty healthy female volunteers (age 19 ± 30 years) with normal menstrual cycle and without any hearing problems are included in this case-control study. Hearing evaluation was performed on the 13th day of the menstrual cycle (follicular phase) and then on the 22nd day (luteal phase). RESULTS: All of the participants had normal results in follicular phase. In luteal phase, four cases showed abnormalities as follows: reduced hearing thresholds 250 Hz (mean= 15 dBHL), increased amplitudes of DPOAE (mean= 3 dBspl), decreased middle ear pressure (mean= -110 dapa), and delayed ABR interpeak latencies (mean of IPLs I-III= 0.4 and mean of IPLs III-V= 0.6 ms). CONCLUSIONS: In some women, changing of ovarian hormones may induce fluctuating hearing and increased progesterone in luteal phase can lead to abnormal outcomes in auditory function. However, elevated estrogen modifies its consequences in follicular phase.
ABSTRACT
Two Fusarium strains, isolated from Asparagus in Italy and Musa in Vietnam respectively, proved to be members of an undescribed clade within the Fusarium solani species complex based on phylogenetic species recognition on ITS, partial RPB2 and EF-1α gene fragments. Macro- and micro-morphological investigations followed with physiological studies done on this new species: Fusarium ershadii sp. nov can be distinguished by its conidial morphology. Both isolates of Fusarium ershadii were shown to be pathogenic to the monocot Asparagus officinalis when inoculated on roots and induced hollow root symptoms within two weeks in Asparagus officinalis seedlings. In comparison mild disease symptoms were observed by the same strains on Musa acuminata seedlings.
